Chichibu Night Festival 2026: Trains, Crowds and Data
Japan 6 min read
The Chichibu Night Festival (Chichibu Yomatsuri) runs on Wednesday 2 and Thursday 3 December 2026, with the 3rd as the main night. It's about 80 minutes from Ikebukuro on the Seibu Laview limited express, and the hard part isn't getting there. It's getting back to Tokyo with a phone that still has signal and battery.
What is the Chichibu Night Festival?
It's one of the big winter festivals near Tokyo. Huge wooden floats, lit by lanterns and carrying drummers, are hauled through the streets of Chichibu in Saitama to Chichibu Shrine and up toward the festival grounds, while winter fireworks go up over the town. The floats weigh several tonnes and are pulled by hand, uphill, in the cold.
The 2026 dates come from the city of Chichibu's notice (updated 13 October 2026) and a Seibu Railway statement of 28 October 2026. The city hadn't published the 2026 procession or fireworks timetable when we checked, so look for it on the city's site the week before.
Which night should you go, the 2nd or the 3rd?
The 3rd is the main night, with the full procession and the long fireworks display. It's also the night with the biggest crowds, the coldest wait and the hardest trip home.
The 2nd, the eve, is quieter. You see floats and lanterns with room to move, and you're more likely to get a seat on the train back. If you've only got one evening and you hate crowds, go on the 2nd. If the fireworks are the point, go on the 3rd and plan your return before you leave Tokyo.
How do you get to Chichibu from Tokyo?
The simplest way is the Laview limited express on the Seibu Ikebukuro line, from Ikebukuro to Seibu-Chichibu Station. The trip takes about 77–80 minutes. Every seat is reserved, and tickets for the festival dates went on sale on 3 November 2026. Those trains fill first, so book the return as well as the trip out.
Slower local trains run too, with a change on the way, and they get packed on festival nights. Coming from Narita or Haneda on the day itself is possible but tight. Most people base themselves in Tokyo and go up for the evening.
Why do phones struggle at a festival like this?
Tens of thousands of people stand in a few streets, and all of them try to post the fireworks at the same moment. Mobile networks there are built for a small town's normal evening, not for that. Expect messages to send slowly and video uploads to stall at the peak, whatever SIM or eSIM you have. No plan fixes a full mast.
What a plan does fix is the rest of the day: the map from Seibu-Chichibu Station to the shrine, the train app when you change your return, the message to the friend you've lost near Hitsujiyama Park. "There's WiFi there" is not a plan. Station WiFi in Japan is common, but it ends at the station exit, and you won't find a hotspot in a crowd on a hillside.
What are your options for data in Japan?
Be honest with yourself about how you travel. All four of these work.
- Your home carrier's roaming. Fine for one or two days if your carrier has a sensible daily pass. Over a week, the daily fee adds up quickly.
- Pocket WiFi rental. Good for a group that stays together all day, because one device covers several phones. At a festival, groups split up, and whoever doesn't hold the router is offline.
- A local prepaid SIM. Cheap for long stays, but you have to swap the card out of your phone and buy it after you land.
- An eSIM installed before the flight. Your phone has data when the plane lands at Narita or Haneda, and your own number still works for calls and texts.
We won't pretend we're cheapest everywhere. For a long stay with heavy streaming, a local SIM or an unlimited plan from another seller may suit you better. HOAM plans are metered, and that's by design.
How much data do you need for a festival trip to Japan?
Maps, train apps, messaging and a few photos posted from the day use little. Video is what eats data. Here's how HOAM's Japan plans line up for a typical trip of a week or so:
| Plan | Price | Lasts | Suits |
|---|---|---|---|
| 3 GB | $11 | 30 days | A short Tokyo trip with the festival evening: maps, trains, messages |
| 5 GB | $18 | 30 days | A week with photos posted every day and some video calls |
| 10 GB | $35 | 30 days | Two weeks, or anyone who posts video from every stop |
Prices in USD, checked November 2026. eSIM prices change; check the current price before you buy. Smaller and larger sizes are on the Japan eSIM page, from 1 GB up to 12 GB.
If you run low, reload at /reload. It's the same eSIM with more data, and there's nothing new to install.
Why install the eSIM before you fly?
Every option except a pre-installed eSIM needs you to already be online to solve being offline. Install HOAM at home, over your own WiFi, and the plan starts working when you land in Japan. Next trip, to Japan again or anywhere else, you load a new plan onto the same eSIM. You'll never install another eSIM.

A checklist for the night
- Book the Laview return to Ikebukuro before you leave Tokyo.
- Install your eSIM at home and switch data roaming on for it.
- Download an offline map of Chichibu, in case the network stalls at the peak.
- Agree a meeting point with your group away from the main streets.
- Bring a power bank. Cold drains a phone battery faster than you'd expect.
- Dress for a long wait outside in a December night in the hills.
Frequently asked questions
When is the Chichibu Night Festival in 2026?
The Chichibu Night Festival runs on 2 and 3 December 2026 in Chichibu, Saitama. The 3rd is the main night, with the full float procession and the winter fireworks.
How long does it take to get from Tokyo to Chichibu?
The Seibu Laview limited express takes about 77 to 80 minutes from Ikebukuro to Seibu-Chichibu Station. All seats are reserved, and festival-day trains sell out, so book the return trip as well.
Is the eve of the Chichibu Night Festival worth going to?
Yes, if you want smaller crowds. On 2 December you see the lit floats with room to move, and the trip back to Tokyo is easier. The 3rd has the full procession and the long fireworks display.
Will my phone work in the crowd at the Chichibu Night Festival?
Expect slow messages and stalled uploads at the peak, because thousands of people use the same few masts at once. Download an offline map and agree a meeting point beforehand.
Do I need a new eSIM for every trip to Japan?
No. A HOAM eSIM is installed once and kept. Each later trip, to Japan or anywhere else, is a new plan loaded onto the same eSIM.
